The Mansfield U. of Penn LCA house was supposedly haunted, I looked on a haunted places in PA website and it was indeed listed there, Im including the notes on here.
Of course this is one of the many many defunct chapters of LCA that will get recolonized one of these years, sigh
"Mansfield - Mansfield University - Lambda Chi Alpha Fraternity House - For years brothers of the fraternity have heard unexplained noises and footsteps throughout the entire house. The apparition of a man appeared in the attack, then vanished. Some students have reported being held face first in their pillow by invisible forces or have felt something sit at the bottom of their bed. The house use to be part of the underground railroad and has had several individuals die within in its doors. People hanging, children playing, choking feelings at night, and many documented past events of people coming to their untimely death haunt this house. "
